VEHICLE-WHEEL.

SPECIFICATION forming part of Letters Patent No. 442,113, dated December9, 1890.

Application filed July 31, 1890- Serial No. 360,480. (No model.)

To all whom it may concern.-

Be it known that I, JOHN E. FISHER, of Boston, in the county of Suffolkand State of Massachusetts, haveinvented certain new and usefulImprovements in Vehicle-Wheels, of which the following, taken inconnection with the accompanying drawings, is a specification.

The invention relates to improvements on the vehicle-wheel for whichLetters Patent of the United States were issued to me February 12, 1889,and numbered 397,711; and it consists in providing the truss in saidLetters Patent with means whereby any liability of splitting the tellyat the joint and spreading it sidewise is prevented and the wheel iskept in better shape. It is carried out as follows, reference being hadto the accompanying drawings, Wherein Figure 1 represents a sideelevation of a wheel provided with my improvements and showing a portionof the felly cut away so as Fig. 2 represents a longitudinal section ofa portion of the rim of the wheel, showing the truss in side elevation.Fig. 3 represents a view of a portion of the outer circumference of thefelly of the wheel, showing the truss and my attached improvement inposition within the felly. Fig. 4 represents a cross-section of the rimof the wheel just at the side of the'joint in the felly. Fig. 5represents a perspective View of the supporting-truss for the wheel withmy improvement attached thereto and showing the same before it has beenapplied to a wheel.

Similar letters refer to similar parts on the different parts of thedrawings.

In constructing wheels in accordance with my original patent abovementioned itwas found that although the supporting-trussprevented thefelly and tire from flattening at the joints in the felly still thereremained a liability of the felly splitting at that place and spreadingwhenever a side pressure was exerted on the felly on account of thedepth of the longitudinal groove in the same for receiving the truss.The object of my present invention is to obviate this difficulty.

The truss a is provided with bearing-plates a a at each end, and is madein the form of a thin piece of metal adapted to enter the longitudinalgroove in the face of the felly to extend nearly, if not quite, theentire distance betweentwo successive spokes b b in the wheel across thejoint between the two sections 0 and c of the telly, and to coincide onits outer face with the inner surface of the tire d, as was shown anddescribed in the Letters Patent above referred to; also, the felly is tobe provided with a clasp eand tirebolts d d, passingthrough the tire,felly, and clasp, having nuts for clamping said parts together, as wasshown in my original patent, and the wheel may also be provided with thebolts or rivets 0 c if so desired, which bolts pass through the fellyfrom side to side and also through perforations in the truss, such boltshaving been shown in Figs. 2 and 3, but not in the other parts of thedrawings, and the use of such bolts will be entirely unnecessary whenthe truss is provided with my improvements, as described hereinafter.

To accomplish the object of my invention, I provide the truss ct withthe side projections a a as shown, one on each side of the truss, and atsuch positions on the same as to cover the joint in the felly, to extenda short distance 011 either side of the joint, and to cause their outersurface to coincide with the outer surface of the telly when they areplaced within the recess in the felly. The projections a (1, whichproject straight out from the sides of the truss, as shown in Fig. 5,are sufficiently long to reach some distance be yond the sides of thefelly when the truss is in position within the recess in the felly, andare adapted to be turned down at right angles over and against the sidesof the telly, as shown in Fig. 4. It will be seen that when theprojections a a are in the position shown in Figs. 2, 3, and 4 they forma clamp on the ends of the sections 0 and c of the felly,pre ventingthem from splitting when the same is subjected to a side pressure, andalso preventing them from spreading sidewise beyond the edge of thetire.

It so desired, the projections a a might be wrought or cast in the shapeshown in Fig. 4 and applied to the felly in'that shape without departingfrom my invention; but I prefer to make them straight and to bend orturn them down on the sides of the felly after telly, and the portionsof the side projections which project beyond the sides of the felly arethen hammered or bent down against the sides of the felly, as shown onthe drawings, clamping the ends of the sections of the telly firmlytogether so as to prevent them from splitting.

Having thus fully described the nature, construction, and operation ofmy invention, I wish to secure by Letters Patent and claiin 1. A supportfor the joint between the sections of the felly of a Wheel, consistingof a truss havingbearing-plates at its ends and projections from theupper part of the sides of the truss, the bearing-plates and sideprojections adapted to be placed Within the folly so as to rest againstthe inside surface of the tire of the wheel, and the side projectionsadapted to rest against and clamp the sides of the felly, substantiallyas and for the purpose set forth. 7

2. In a vehicle-Wheel, a supporting-truss introduced within a recess inthe face of the felly, extending across the joint between the sectionsof the telly, and side projections on the truss, projecting beyond thesides of the felly and adapted to be bent or turned down against thesame, for the purpose set forth.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, on this 28th day of July, A. D.1890;

JOHN E. FISHER. \Vitnesses:
